However I have hit a brick wall. I am currently working on the localised version as opposed to networked. Basically -- I have my main in my GUI which immediately initialises my Data.java constructor. This class contains my methods such as FindByCriteria etc.
Basically -- where do I open and close my file in the Data class given that my methods(findByCriteria etc.) have to be able to see the file? Obviously I can't have my methods in the constructor. But when my methods are outside the constructor it can't see the file -- even if i don't close the file -- as the methods are outside the try-catch of the IOException.
I feel I'm in a catch 22. Surely I don't open and close the file within each method? I'm assuming the file need only be opened once.
That' realy depends on your decisions/architecture/mechanism. If you gonna cash the information them you only read the data file once but there are also other solutions.
